We present a series of four webinars, starting with an introduction to the software, then covering EDS Mapping and Chemical Imaging, and finally using WDS with Pathfinder software. Requires registration. Welcome to Pathfinder EDS Software (50 minutes) All About EDS Mapping with Pathfiner (40 minutes) Extreme Element Mapping and Chemical Imaging (55 minutes) WDS Speed […]

This presentation shows how to make quick work out of quantitative analysis of materials such as a metamorphic rock. We walk through the steps to collect WDS quantitative data from minerals in a contact metamorphosed calc-silicate rock. Thanks to routines built into the WDS spectrometer and simultaneous EDS and WDS acquisitions, plus stage automation WDS […]

Recent developments have made wavelength dispersive X-ray spectroscopy (WDS) much more accessible to SEM/EDS work. In this presentation in X-ray microanalysis, we present the modern way to do WDS. Thanks to improved X-ray optics and better mechanical operation, what was once painstaking slow and difficult to use has become as easy to use as EDS. […]

Mapping phases by simply relying on X-ray maps, or using a spectral matching method, require subjective inputs into the analysis. We explore mapping apatite and zoned monazite grains. Using principal component analysis (PCA) software, we produce rich spectrum-based phase maps acquired with no input regarding the composition of sample—the PCA software does all the work. […]

WDS is the perfect complement to EDS. The unmatched energy resolution and low backgrounds of WDS make it the ideal technique for the definitive identification of the elements present in a sample and the quantification of elements down to a concentration of ~0.01 wt%. We cover several confounding X-ray interferences in EDS and show how […]

One of the greatest challenges in SEM-based microanalysis is managing interfering X-ray lines. We review the quantitative analysis of a Ti-V-Al-Fe sample consisting of two phases with only small differences in V and Fe content. We cover a number of possible techniques to resolve X-ray lines line separated by only 17 eV. Neither EDS alone, […]

Spectral imaging collects a full energy spectrum at each pixel in your image. Faster acquisition times and increased automation have made it one of the more commonly used microanalytical methods in SEM. We use a lunar meteorite to review the many mapping methods that spectral imaging data provides. Our review includes elemental mapping, semi-quantitative elemental […]

This presentation is a fast-paced demonstration of our Thermo Scientific™ COMPASS software. COMPASS is a fully automated statistical analysis tool that eliminates any chance of misinterpretation of the data, and the possibility of your publishing incorrect results. See how you can quickly create phase maps that pin-point the critical features in your sample. Learn how any […]

The Electron Probe Microanalyzer (EPMA) sets the standard for spectroscopy excellence in electron microscopy. The Thermo Scientific™ NORAN System 7 is designed for rapid results with EDS and quickly surveys large sections of the sample across the entire energy spectrum with acquisition times 100 times faster than the WDS. It operates effectively at low accelerating […]

Feature Sizing with Chemical Typing software facilitates the identification and characterization of small particles or inclusions sparsely located throughout a matrix. This presentation shows how to measure, count and identify particles, inclusions, phases and regions of interest within the sample, and identify and save particle classes Run time: 30 mins Recording date: 4/9/2013 View webinar […]
